Specification of Letters Patent.

Patented Aug. 1i, 1908.

Application filed October 25, 1907. Serial No. 399,129.

To all whom it may concern:

Be it known that I, UBALD HEBERT, a citizen of the United States, residing in Manchester, in the county of Hillsboro and State of New Hampshire, have invented new V and useful Improvements in Weft-Replenishin Looms, of which the following is a speci cation.

. This invention relates to that I class of looms in which a fresh sup ly of fillin is provided at the proper time y means 0 an automatic filling-supplying mechanism; and the resent invention relates to certain novel mec anism and arrangements of parts whereby when the filling has been nearly exhausted, an electrical circuit is estabwhich my invention is applied, and a portion of the shuttle and portions of parts mounted on the shuttle-box next the path of the shuttle being represented in horizontal sect-ion. Fig. 3 .is a section taken on line 3-3, Fig. 2, looking toward the left. Fig. 4 is a section taken on line 4'4, Fig. 2,1ook1ng toward the rear. Fig. 5 is a lan of a por tion of the bobbin removed. ig. 6 is a section taken on line 66, Fig. 5 Fig. 7 is a cross section of the shuttle removed with the pgpbin left in position, looking toward the Similar numerals of reference indicate-corresponding parts. eference numeral 10 represents the lay, 11 is the breast-beam, 12 is the notched holding-plate (Figs. 1 and 2) attached to the,

breast-beam and provided with the ordinary shipper-lever 13, 14 is the fillin feeder constructed to receive the ends 0% carriers 15, and 16 is a transferrer mounted on the stud 17all the above parts bein operated in the manner well known in t e art, and none of them being new in this invention.

18 represents the shuttle-box, and 19 the shuttle contained therein, said shuttle being provided with the bobbin 20. The bobbin in addition to the usual rings 21 is provided zonta the filling-.

with two rings 22 and 23, the former being nearerthe head of the bobbin than the latter. See Figs 5 and 6. Embedded in a horizontal oove on the under side of the bobbin is a wire 24 which is secured in position by its ends 25, said wire being in, permanent contact with the wire rings 22 and 23. See

. Figs. 6 and 7. On the up or side of the bobbin there is a longitudinal groove 28, and in theouter end of this groove there is secured by means of its bent portion 29 a springwire, the portion 30 of which is straight, the.

portion 31 of which is curved downward into a correspondingly shaped recess 32 in the bobbin whereby it is out of contact with the ring 22, and\the portion 33 of said wire extends downward on an inclineunder and in normal contact with the ring 23, said portion lying in the deep groove 34, and being nor mally held up into j said contact by its springing quality. A deep notch 35 is provided on the upper side of the bobbin and beneath and on opposite sides of the portion 33 of the spring-wire in the groove 34',

whereby thepressure of the filling on the bobbin above that portion of the sprmg-wire 33which is next said notch will force the spring-wire down into the deep groove 34 until the amount of said filling becomes so slight as not to overcome the upward ressure of the s ring-wire-as below descrlbed.

The shutt e 19 is provided onthe outer surface. of its front side with two sets of horizontally disposed metallic plates, each set consisting of an up er and a lower plate separated from each 0t er, and the pairs of ,plates being separated from and in line with each other. See Figs. 2 and]. The right hand air of plates consists of an upper horil late 36 and a lower horizontal plate 37 flus withthe surface of the shuttle.

The plates 36 and 37 are provided with 7 horizontal extensions 38 and 39 respectively -which project through the wall of the shuttle Mounted on the la next and in front of the path of the shutt e, and secured thereto by'suitable bolts "43 and ears 44 is a horizontal' metallic frame 45, preferably a casting, and this frame has secured to its posite ends a leather covering 46 made suffi diently smooth to avoid unnecessary friction and to i e revent wear of the side of the shuttle.

ordinary manner as illustrated The two and 48. The binding-post 54 is connected shanks 51 and 52 of the springs 47 and 48 are secured respectively by binding-posts 54 j and 55 to the frame 45 within the slots 47 by a wire 56 with a battery 57 which is connected by a wire 58 with a suitable electromagnet 59, said magnet being connected by a wire 60 with the binding-post 55. The magnet is mounted on a frame 61 which is bolted at 62 to the stop-motion slide 63 bolted at 64 to-the breastbeam-said slide not being new in this invention. Extending upward from and integral with the frame 61 are a pair of cars 65, and pivoted at 66 to and between said ears is a swin 'ng arm 67 which is curved downward as il ustrated in Fig. 4 and has secured to its broadened lower end 68 an armature 69 which hangs normally down in the position indicated near the magnet 59. I

Integral with the left hand pair of plates 42 on theshuttle is a metallic extenslon or bar 70 (Fi 2) from which a bolt 71 extends horizontal y throu h the head ofthe shuttle, and connected wit this bolt in the ordinary manner is the usual metallic filling-carrier or bobbin-carrier 72, the jaws of which are in contact with the rings 21. As therings 21 are in contact with the wire'30, 33, and as the rings 22 and 23 are in contact with the wire 24, it is evident that if the shuttle were in its box and the spring-wire 30, 33 were allowed to spring up into contact with the ring 23, asin Fi s. 5, 6 and 7, the electrical circuit would inc ude the wire 60, the binding-post 55, the shank 52 and spring 50, the upper right hand plate 36, and extension 38 (or the lower right hand plate37 and extension 39 in case the shuttle should be raised), the vertical bar 40, the s ring 41, the metallic ring 22, the wire 24, t e metallic ring 23,.

the spri -wire 30, 31, 33, the s 21, the filling 0r obbin-carrier 72, the b0 t 71, the

bar or extension 70, the upper of the left "with the ring 23,

hand air of bars or plates 42 (or the lower shoul the shuttle ha pen to be. raised) the spring 49 and its shan 51, the binding-post e i 54, the Wire 56, battery 57 and wire 58 connecti with the magnet. When, therefore the be bin is empty, as in Figs. 5, 6 and 7, there is nothing to revent the s ring-wire 30, 33 from lying up 1n contact wit the ring 23, and theabove 'describedcircuit is established, energizing the ma net 59 and causing the armature 69 to be rawn against it; but when there is enough filling left on the bobbin to press and hold down the springin the path of the lug or projection 74 which extends horizontally toward the'left from the outer end of the rocking-fram 75 ivotally mounted at 76 on the suppoi'ting1 lock 77 which is mounted on and rigid wit zontally sliding bar 78 which slides in a way 79 making apart of the stop-motion slideway. The rear end of the rocking-frame 75 has pivoted to it at 80 the upper end of a latch 81 which is adapted to e enga ed in the ordinary manner by the upper en 82 of the stop-motion lever83. The front end of the bar 80 is ivotally connected at 84 with the downwar y extending U-shaped arm 85 provided with the horizontal rojection 86 lower portion of this arm 85 is rigid with the rock-s aft 88, and its extreme lower end is connected with the 3 ring 89 which extends to the frame. Loose y mounted on the rockshaft 88 is the arm 90 whose lower depending end 91 is adapted to throw out the takeup mechanism in the ordinary manner, its upper end being in 'enga ement with t. e notched portion92 of the ock-ofi lever 93 the hori-- which bears against the breastearn 11. The

which bears against the; shipper-lever 13.

None of the above described parts numbered from 75 to 93 inclusive are new in this invention, but operate in a mannerwell known to the art, the extreme end94 of the knock-off lever bein adapted to be e gaged by the slide 95 w en' a weft-thread breaks-all as usual; the drawings showin the weft-ham ing" 98 on the bobbin and in the notch 35 to press down the'spring 30,33 out of contact breaking the circuit. As soon as the has been removed, or is so nearly exhausted as not to overcome the power of this spring, said s ring rises into 1 contact with the ring 23 an closes the ciri said cam or projection, is free cuit (as above mentioned),

the position of the spring being indicated in Figs. 5 to 7 inclu sive. As soon as this circuit is thus closed the armature immediately swings into contact with the magnet, drawing the projection or cam 73 out of the path of the lug 7 4 which,

,stop-motion lever 83, rotating the shaft 88 rockingame, latch, slide,

means of the arm 85 and thus operating the fillin -mechanism. The operation of this arm, shaft, and filling-mechanism are not new in this invention, but are known in the art, and a'descrip- United States tion ofasaid operation may be found in Letters Patent numbered 859,208, in which the operation is actuated by a feeler, while in my present invention it is actuated or allowed to operate by the swinging of the armature out of engagement with the magnet. After this operation has been completed, it being so timed as to take eflect immediately on the drop of the armature, the circuit still remains open while the I shuttle is returning to the position indicated provided with a. shuttle mechanism, the lay,

in the drawings, and continuously until the filling is so nearly exhausted as to allow the spring 30, 33 to rise into contact with the ring 23. o Q

As above indicated, the object of providing parallellower plates as well as the upper plates 36 and42 on the shuttle, is to allow for the fact that the shuttle rises from its ordinary position in the box.

Having thus fully described my invention, what .I claim, and desire to secure by Letters Patent is A I 1.
